Special Event Station

We could apply for an NOV for a special call sign for a special event station, for example GB2EMF. The question is whether enough people want to operate to keep the station going for the bulk of the weekend. It's unlikely that anybody wants to spend a significant proportion of their weekend running the special event station.

Milton Keynes ARS (MKARS) are literally just up the road from the campsite

Repeaters

It would be very cool to have a dedicated on-site repeater just for EMF. The practicality wouldn't be too difficult -- M0RND can provide a 2m/70cm colinear (which might be able to be hosted on the main EMF mast), and there's no shortage of radios which can do cross-band repeat, or something could be lashed up with two Baofeng UV-B5 radios and a diplexer.

The awkward part would be getting an NOV for the repeater, and getting it in time for EMF.
